Tried some new techniques (borrowed some ideas from a tutorial).
The map took about 5 hours to make (not counting preparations).
5200x5300 pixels. The "correct" size to see the map would be about 1/3 of this size (map made for print).
One pixel is 10 metres.
Used mainly layer styles for this map (+ some shadowing etc).
Comments welcome as usual. I know there are some minor errors on the map but I have to start my mapping my project.
EDIT: fixed some minor stuff on the map.
